Default Parmeter pass through

It would be nice if the Defaultiness of optional parameters was passed through to functions called by a function with a default parameter.  For instance with this code

function Func1([defParm])
  variable defParm
  return func2(defParm = defParm)
end

function Func1WorkAround([defParm])
  variable defParm
  if (ParamIsDefault(defParm))
    return func2()
  else
    return func2(defParm = defParm)
  endif
end

function Func2([defParm])
  variable defParm
  if (ParamIsDefault(defParm))
    print "Default"
    return 0
  else
    print "Not Default"
    return 1
  endif
end

 

You get the following results

 

•func1()
  Not Default
•func1WorkAround()
  Default
•func1(defParm=1)
  Not Default
•func1WorkAround(defParm=1)
  Not Default

 

The workaround works fine, but when you start to have multiple default parameters it gets cumbersome
